^*1 Data prepared by Panasonic. The effect differs depending on operating conditions, and the type, condition and amount of food stored. ^*2 The time required to reach the maximum ice crystal formation zone (-1℃ to -5℃) is about 28 minutes. Test conditions: 150g of beef steak (shank cut) covered in cling wrap on an aluminium place placed in the Prime Freeze compartment with Rapid Freezing. External temperature was 25℃, opening/closing of the door was prohibited (in-house measurements). These features are available on the Prime+ Edition series. ^*3 Testing organization: Kitasato Research Center for Environmental Science (general incorporated foundation). KRCES－Bio. Test Report No. 2017_0188. Test method: After releasing floating bacteria (1 type) in a 400 L chamber, the number of bacteria in collected air were counted. Bacteria inhibition method: Release of nanoe® X. Test results: With nanoe^® X , after 50 min, 99.99% more of bacteria inhibited. Does not guarantee the prevention of food poisoning. ^*4 Comparison of the freshness of vegetables in vegetable compartments: Comparison of the vegetable compartment with Moisture Control Filter and the vegetable compartment without Moisture Control Filter. Air temperature outside the refrigerator of 25ºC. No opening/closing of doors. Vegetables stored unwrapped in fully loaded compartments. The number of days items can be stored and their freshness changes depending on the type of vegetables and their condition when placed in the refrigerator. ^*5 Panasonic in house data. Ambient temperature: 32℃, when the temperature setting of the refrigerator is “MED”. Door opening/closing frequency: fridge compartment 35 times, freezer compartment 7 times. Load: 1750 kg test package in the freezer compartment, 2.5L of water in the fridge compartment. If there is a power outage, ECONAVI function may not operate normally. ^*6 Panasonic in house data. A comparison of the PRIME+ EDITION YW590 and the NR-B41M1, a conventional non inverter Panasonic model. The energy consumption level is based on Vietnam standards..
